The Microsoft Azure Multitenant SaaS .NET Sample Code by Danny Strockis demonstrates how to build an MVC web app that uses OpenID connect to sign up. The steps to run the sample cover cloning or downloading the repository, registering the sample with an Azure Active Directory tenant, provisioning a key for the app in your Azure Active Directory tenant, and configuring the sample to use the Azure Active Directory tenant. Before running the sample, an optional step is creating an Azure Active Directory test tenant.
